To @ZZ w hom t may concer/n,.-

Be it known that I, KATHERYNE P. Munn,

a citizen of the UnitedStatesanda resident of the city of Chicago,county of Cool-:,'and State of Illinois, have invented certain new l and'useful Improvements in Presses, or

which the following is a specification. My invention relates toimprovements in.

presses7 and more especially to `iiltering means for'ltering liquidsexpresse'dby said presses,l the object of' the invention being toprovide a siinpleandr eiective arrangement of this character whichls/ofsimple V construction and efficient in operation.

Other objects will appear hereinafter.`l`

The invention consists in' theconribinations`.v

and arrangements of parts hereinafter described and claimed.-l y n.

The invention vwill 'be best 1understood by reference to theaccompanying drawings forming a partof this specification, and in which,Y

Fig. 1 is a partial side view ofr a portion' of the hydraulic pressembodying the invention; u v

Fig. 2 is a transverse section of the; same bag lemployed intheconstruction;

Fig. t is a section taken on line of Fig;

Fig. 5 is a bottoml plan view co'.rresp'onding with Fig. 3; and.

Fig. 6 is a section takenon line 6-6 of Fig.3. i f

The preferred form of construction as illustrated in the drawings`comprises the usual horizontal hydraulic press having the usual sidebars 7 and abutment 8 with the usual pressure frames 9 arranged asindicated, each frame 9 being formed of vertical and horizontal slats asshown, one horizontal `slat 10 being extended laterally to rest upontheside bars 7 as best indicated in Fi'gp). So much of the construction"is'an old and well known form of construction employed in such pressesfor expressing liquid matter from meal'7 ground meat, or the like yandforms no part ofl my present invention except in so far as the samecooperates ywith other features to be presently described.v

Each of the pressure frames 9 is provided at the bottom `on oppositesides with hooks 11 adapted to detachably engage pins 1201/1 theadjacentframe and whereby said frames may be readily positioned in the press vin4spaced relation with each otheLEach.) the lpressure frames 9 is`alsoprovided' at. its bottom `with a horizontal cross slat-1`3forin-`ing a supporting `ledgev as indicated anda' cloth filter bag 14 isarranged lbetweenfeach` v pair of the pressure members Each. filter bagis made tubular inform .and open atf j both top an'd'ibottom,beingiprovided at the l I .the bag may be secured in place between twoftop with sidev flaps 15 by ineainsof which of the pressure frames- 9 bytacks orv other-V wise as indicated. At the bottom each 11", i isprovidedjwithA upwardly turned flaps 16` forming loops as shown for thereception of l stiifening plates 17 arranged in said loops acrossopposite sides of the bag as shown. i

1n use each bag is .foldedor v"wrapped i around the stilienin'gplates-17 and positioned lbetween the-'pressure' members 9-as in-v Idicate'd with the platesnl supported 'on corresponding strip 13 in" aninclinedpositionf as shown, the hooks-11 being utilizedjtohold thepressure vrnembers 911in-properfspaced relationto supportthe. plates 17in s'uch'finlf clined position/The bag 14 is; then filled or the likefrom which it isdesired to `ef;- press the vliquid and the pressoperated toi with the materiah such as cotton seed meal i force theframes 9 towardy each. other ythus A' compressing the `matter Iin ithebags ltvand forcingtheliquid through the walls of the f i bag.

L therefore, do`not wish to be limited to the vprecise detailsl of the construction setforth.,` y

but desire to avail myself of such variations and modifications as comewithin the scope of the appended claims. f

Having described my invention, what l claim as newand desire to secureby Letters Patent is members; a filter bag inserted betweensaid 1.- Apress comprising adjoining` pressure members; and a filter bag` offlexible materialinserted between said members, said bag being openatone end and a complete portion of the open lend of said bag being,folded upon itselfand 4arranged between said pressure members so as tocause said complete vfolded end to press against the side of said bag,`upon the approach of vsaid .pressure members, substantially asdescribed.

2. A press comprising adjoining pressure members, said vbag` being openat one end ;l a st ili'ening plater arranged at tlie open end of .y saidbag, said bag being folded against yone side of said plate; and meansfor support-I ing` said plate between said pressure nienibers in aninclined position, substantially as described.

3. A pressl comprising` adjoining pressure members; a filter bag:Tinserted between said f members, said bag being` open'at one end; a

.stiii'ening plate arranged at the open end of said bag, said bag beingfolded around and against one side of said plate; and means for su aortino' said late between said aressure members in an inclined position,substantially as described..`

Il. A hydraulic press comprising adjoining pressure members; a filterbag inserted between said members, said beingopen at its lower end;stiflening plates secured to y opposite sides of said bag adjacent tlieopen sides of said bag adjacent the lower end' thereof, saidV bag beingfolded around said plates; means for supporting said plates between thelower portions'of said pressure members `invvan inclined position; anddekti ally as described.

tachable means for securingksaid pressure members in spaced relation toleach other, substantially as described. f 6. A press comprisingadjoining pressure members; a cloth filter bag arranged between saidmembers, said bag being open at the bottom; stiffening plates secured tooppositev sides of said bag` at the lower end thereof, said 'bag plates;fisupporting ledge on one of said pressure members adjacenttlie bottomtliereofadapted and arranged to support said plates in an inclinedposition between said pressure members;` and'y detachable hoolrssecuring` said pressure 'members in spaced relation to eacli other,substantially as described.

7, A filter bag for presses lmade with a normally open'end and astiflening plate ai."-v ranged across one side of said bag adjacenttheopenend thereof, said bag being adapted and arranged to be' foldedagainst one side of said plate for sealing` purposes, substantially asdescribed.`

8. A filter bag for presses open at the bottom; and stiffening platesarranged across' oppesite sides of said bag adjacent the bottom thereof,saidplates being arranged to be folded againstlthe side of said ba?,-for sealing purposes, substantially as described. y,

9. A filter bagl for presses comprising` a tubular cloth bodyopen atboth top and bottom; and a stiffeningplate secured across one side ofthe bottom of said bag, substanlO. A filter bag for presses'comprising atubular cloth body open at both topand bottom; and stiffening platessecured across onposite sides of thebottom of said bag, sub stantiallyas described. i n

ll. A filter bag for presses made of flexible material and normally openat one end,

acomplete portion rof the open end of said bag` being folded upon itselfand arranged to press against the side of said' bag, substantially asdescribed. Y
